BIOL 205 Study Guide - Midterm Guide: Single-Nucleotide Polymorphism, Sister Chromatids, Chromosome Segregation
Document Summary
Single nucleotide polymorphism single nucleotide polymorphisms (snps), the most common type of variation in most, if not all, organisms. Biological research focuses on how organisms develop from a fertilized egg into an adult . Aka what makes an organism the way it is. In order to figure that ^ out, they study individual biological properties like the development of plant flower colour or animal locomotion or nutrient uptake as well as more general things like how a cell works. Gene discovery: finding genes that influence that property. After, these genes have been identified, their cellular functions can be determined with more research. The basic approach of genetics is to compare & contrast properties of variants, and from these comparisons make deductions about genetic function. Wild type: most common form of any property. Mutations create mutants and result in a heritable change in the dna of the gene. Polymorphisms: coexistence of two or more reasonably common phenotypes of a biological property.
